第２７冊。なぜ、この世界に学問と呼ばれる領域が存在して、学問が学問たり得たのでしょうか。 Why does the field known as scholarship exist in this world, and why has scholarship been able to exist as scholarship?

 こんにちは。渡辺天です。お願いします。今回のテーマは価格付けです。価格付けというとセーの法則を思い浮かぶ人もいるでしょう。セーの法則とは、経済学で言うところの超過需要経済であり、人々が欲しいと思う気持ちが供給したいという気持ちより多い経済を言います。

僕たちは、この超過需要経済でセーの法則という現象に出くわします。セーの法則とは、供給すれば、つまり売れば売るだけ売れる経済のことを指します。今、あなたは工場の生産者として一定のノルマを請け負っていることとしましょう。これだけの製品をこれだけの納期で生産してほしい、と。

普通、僕たちのいる経済であれば、生産しても売れない商品は在庫となって倉庫に眠ってしまうでしょう。一方、セーの法則の世界では、売れ残りの商品がなく、生産した商品がすべて売れることになります。

現実の世界と理論の世界では、一種の乖離という現象に出くわします。乖離とは、少しずつ差が広がっていく現象であって、多くの差ができる頃にはかなりの時間が進んでいることであると言えます。学問の世界でも最初の理論から現実世界とは大きく乖離していく現象に出くわすことがあります。最初は古典派の利己主義といった仮定といえる前提が理論を積み重ねるに連れ、段々と現実から乖離していくといった現象です。

僕たちは科学や学問という世界に出会うとき、なぜ、その理論がその理論であるか、よく理解する必要があるということです。最初の設定が無理な話であると、その後の話もだんだんと無理が積み重なっていくことになります。

最初の過程はきっと現実というものを理論化したいという欲求だったのでしょう。しかし、その欲求も試行錯誤を重ねて次第に力技となっていきます。理論も複雑で高度なものとなり、普通の一般の人では理解できないものとなっていきます。

量子力学を見ましょう。最初は、ただ光というもののグラデーション、つまり濃淡を数式化したいという欲求だったのでしょう。数式が難しくならないように変数ｘ変数の２次式の足し算でこの光のグラデーションという難題に取り組んだことだと思います。

しかし、時代が進むにつれて微分方程式やかの有名なシュレディンガー方程式など、最初の観測実験と呼ばれる光の観測から、あるいはシュレディンガーの猫と呼ばれる確率論の話から土台が揺らいでいたことに気づくことになるのです。

量子力学が確率論であるのは、なぜかというと速度や位置が同時に確定しないからで、そもそも光というものが観測できるスピードのものでないので、想像の域で理論を展開しているからです。

あの有名な相対性理論を生み出した某氏も頭の中の思考実験により光というものの解析に取り組んできたのです。その某氏も量子力学の生みの親の一人ですが、僕は価格式に至っても、この観測可能な経済現象にしても長らく思考実験の域を出なかったのではないかと考えています。

経済というものが需要という効用により、あるいは欲しいという欲求により、その価格式を理論化していたように、科学も長らく力技で現実を数式化してきたのではないでしょうか。その数式化したものを操れば、色々なものに、ここでは帰納と演繹に対応することができたと思います。

ここで言う、帰納と演繹とは、帰納という法則化、つまり現実を数式化してシンプルに表すことから、その数式を色々な経済現象などに適応して応用する、つまり演繹化することに価値を見出したのだと思います。

僕は一重に言うでしょう。なぜ、この世界はこのように数奇なのか。なぜ、この世界に学問と呼ばれる領域が存在して、学問が学問たり得たのでしょうか。学問も最初は単純な構造から始まっていますが、なぜ未だに現実をなぞることに多くを費やしているのか。

最初のテーマに戻ります。価格式のセーの法則の世界では、価格は恐らくとても安価なものでしょう。在庫が存在せず、廃棄がなければ、価格転嫁する必要がないからです。しかし、現実世界はセーの法則とは違い、少なくとも現代では多くの商品が買われることもなく廃棄されていきます。

この無惨な世界に一つの希望は廃棄をなくし、セーの法則に近づけることで、セーの法則がある程度の需要を含んでいるのであれば、一つの理想郷であったと言えることです。その点では、商品を作れば、すべて売れるということに世界の一つの理が体現されているのかもしれませんね。以上です。ありがとうございました。渡辺天でした。

page 3 !! You may have spent the last five years living the same routine, but the day will come when the things you've diligently built up over those five years will be recognized. -R86plusA-

Hello. This is Ten Watanabe from R86plusA. What is the purpose of a human life?

From infancy to old age, a person begins at zero and ends at zero. During this time, what is gained, and what is lost?

It's human nature to want to acquire as much as possible while you're alive. There's no stability in a life lived haphazardly. I'm not sure if "stability" is the right word, but even people who treat their lives like a gamble might be seeking the stability of possessing many things.

Stability is good, but it's not good if it holds you back. Growth follows stability, and stability follows growth. People are likely seeking a sense of stability in society.

People want things to be predictable and for things to proceed in a natural way. They hope that no unforeseen events occur when people seek stability. They earnestly hope that they can avoid accidents through their own efforts.

I feel uneasy about living day to day without building anything substantial. I don't need to climb Mount Everest, but I want to aim to be one of the top-ranking mountains in my country.

If you gain experience successfully, you have the potential to conquer even the highest mountain. Some people might lose motivation when told to build things up little by little. Whether you become motivated or discouraged when told you have to work hard for another five years depends on the individual.

Amidst all of that, the day will come when the hard work you've diligently put in over five years will be recognized. You may have felt like you were going about your daily life as usual, but five years will surely feel like a very long time.

The more intense your efforts become, the more you are at the mercy of the passage of time. However, if you continue to perform brilliantly on stage five years from now, you will eventually reap significant rewards. At that point, you will be faced with two choices.

The question now is whether to seek stability and play it safe, or to continue for another five years and challenge yourself to reach an even higher peak. Humans are not simple creatures. When fortunate enough to be faced with these two choices, whether to play it safe or to push forward will vary from person to person.

As for myself, I want to live a moderate life, neither playing it safe nor going on the offensive. If I've been able to persevere for five years, then it shouldn't be impossible to persevere for another five years ten years from the start.

While athletes face age-related limitations due to declining physical abilities, intellectual abilities have the advantage of becoming more refined with experience.

Even intellectual ability sometimes requires physical strength, but there are diverse ways to fight, including both. What will remain after 5, 10, 20, or 30 years? We may be faced with a choice.

page 2 !! Because it's a world of self-satisfaction, the result of dividing by 1 to average out one sample—so to speak, one person is both ordinary and special—can be anything. -R86plusA-

Hello. This is Ten Watanabe from R86plusA. I have a living bible.

In religious terms, this could be a renowned monk, or even the founder of a top-tier company. As they age, they accumulate more experience and generate new ways of thinking.

When that person speaks, everyone listens intently. A living Bible can be said to be someone who, having weathered the storms of everyday society, neither falls nor runs off, but simply fulfills their mission.

What is a mission? It is a destiny assigned to a person, a life only they can fulfill. Those with a mission make many sacrifices. They are people who live unique lives, not ordinary lives.

Was that mission something that descended from heaven? Or was it something that they truly wished to achieve in order to survive in everyday society?

Each person's destiny is different. There is no superiority or inferiority among them. However, it is abundantly clear that a stronger mission will prevail over others.

There's no way that a mission achieved through relentless effort and dedication won't be realized. Once it's achieved, a new mission will surely stand before you. By carefully accomplishing each of these missions one by one, you will move closer to your ideal state.

Having ideals is good, but it's not essential. Even if your actions seem like spur-of-the-moment solutions, as long as you have a general idea, the results of your actions will eventually settle into their intended form. Comparing your personal goals to those of others is meaningless; they are ultimately a matter of self-satisfaction.

However, because it's self-satisfaction, it's like dividing one sample by 1 to average out the idea that you are both ordinary and special. One person's result divided by 1 can be anything. Someone thinks they are special because they are doing something special.

Even beautiful people cannot remain beautiful without any effort. If that's the case, then it's impossible that someone living an extraordinary life isn't putting in some effort.

In the sense of living one's own life, one can only judge one's own life subjectively, because one has not lived any other person's life.

Furthermore, those who believe their own lives are unique to them and that their own thoughts are their living bible are truly fortunate.

There's no point in comparing yourself to others. Since no two people are exactly alike, comparing them is pointless because the standards are completely different.

Before you get consumed by petty jealousy or pride, I want you to stop and think: Why is that person special? That person does special things in order to be special.

If you can understand that, you should be able to make your own life something special without interfering in other people's lives. Of course, you should only listen to other people's opinions, including mine, as reference.

So, what will you accomplish next? That might be the problem you're currently facing.

page 1 !! First point! In my opinion, there are many things that are most important to human beings, but among them, the most important is "memory," and without memory, that is, knowledge, we can't do anything. -R86plusA-

Book 26. I think stereotypes are a good thing, and depending on how they are used, they can be interesting and be as the basis for new discoveries.

 Hello. I'm Ten Watanabe. Thank you. Today's topic is economics. I'd like to talk about the relationship between sales volume and production volume.

Sales volume refers to the amount of goods or products sold. Both goods and products have different meanings, and in the field of economics, they are used differently, so if you're interested, please look up their meanings. I'm sure it'll be interesting.

The quantity sold is interesting to you because the quantity sold is demand. Economics, at least microeconomics, does not have the concept or idea of ​​quantity sold.

However, if we bring in the concept of sales volume, the more you sell, the greater the demand and need, and it is natural to think that you should produce and sell more. In other words, it is common sense to think that when there is a need for sales volume, production volume will increase.

Here, I would like to talk about common sense. Common sense refers to strong fixed ideas, or stereotypes, that are ingrained in us through our everyday lives and can be considered stigmas. These stereotypes are so firmly rooted in our minds that when we try to think in a new way, they get in the way of coming up with that new way of thinking.

Stereotypes are surprisingly useful ways of thinking. When classifying something or making a snap judgment, they can save a lot of time because they allow you to classify it instantly. I have always been skeptical of stereotypes.

As a blogger, I am also an artist, a writer, and a bit of a creator. The thing I fear most when blogging is running out of new ideas. Getting stuck in a rut usually happens when you get stuck in a stereotype and can no longer think of new things.

I know that common sense is extremely inconvenient when it comes to making great discoveries, and that there is value in temporarily setting aside common sense.

Even in this topic of economics, there was macroeconomics, a field of economics founded by Keynes, but in order to address the problems that arose when trying to combine macroeconomics and microeconomics, known as the microfoundations of macroeconomics, the mainstream Keynesian economics of the time was abandoned.

I studied new economics quite a while ago, so my memory is a bit hazy, but it became a science of prediction, such as the New Keynesian model, and it abandoned previous economic policies, namely macroeconomics, which treated the economic adjustment function of built-in stabilizers as the main economic policy.

It can be said that macroeconomics was a case of abandoning the accepted economic thinking and starting afresh with new theories such as the New Keynesian model. However, I do not think that Keynes's macroeconomics was a completely superior theory and was by no means meaningless.

This time we talked about Keynesian economics and common sense, but I think common sense is not something that exists. Just as common sense is common sense, stereotypes do not stop stereotypes. The difference between common sense and stereotypes is related to prejudice.

Common sense is an orthodox way of thinking that takes a middle path, but stereotypes are more rigid ideas than orthodox, and many of them contain prejudice. Just as common sense is the direct path of the royal road, stereotypes include direct views, but also prejudices that deviate from that.

In that sense, our common sense is not a biased way of thinking, but rather it is the mainstream, and so it is difficult to discard it. I think that this mainstream way of thinking should be preserved.

Conservative thinking is necessary, but stereotypical thinking that includes prejudice is also necessary in some cases. This is because prejudice is randomness and nurtures the seeds of new creativity. I believe your generation is a good generation. Just as it was in my generation, your generation should also be one in which new discoveries will renew society for the better.

We may be living in the same era, but we are also living in different eras, because we have different ways of thinking, different senses, and different sensory organs. However, as I've said at length, I would say that stereotypes are a good thing.

While stereotypes are strong ideas that can be discriminatory in themselves, I think it's interesting that, depending on how they're used, they can serve as the basis for new discoveries. I'd like to take some time to think again about the difference between seemingly conservative stereotypes and new discoveries.

If I have the opportunity, I would like to delve deeper into this point in the next rewrite. I will find the answer by then. That's all. Thank you for your growth. This was Watanabe Ten.

Book 25. Novel. Ace of Hearts. This is Beta. I've decided to become king in the dream world. Don't get in my way.

  Hmm. Why? β suddenly recalls the happy days of the past. Trips he took with his family, days when he returned home to see his grandparents. For some reason, tears well up in his eyes. Why did I run away from studying?

Beta. This is Kota. Your Alpha group is lively, but Misaki is worried about Beta going out of control. Why hasn't Beta been coming to school lately? What is he doing now? I'd like to know.

This is Beta. I don't need to go to school anymore. I've already attended enough days, and I don't see the value in studying at school anymore. Instead, a fun playground has opened, and I work there. It's a volunteer job, though.

This is Miyori. As Kota said, I want the betas to come to school. It seems like you have a lot of secrets, but I want you to come back. The alphas in your beta group are making a fuss, saying that your alpha group is in danger of collapsing. What are you doing now?

This is Beta. Please leave me alone. What I'm doing now is always lying down and sleeping. Just sleeping. I might not be feeling too well. There's something called a dream world. You guys might not understand, though.

Lately, my dreams have become unusually real. They're called lucid dreams, and although I know I'm dreaming, I've become able to move freely within them. While I'm asleep, it's so real that I can't distinguish it from reality. It feels the same as when I'm awake. But I know I'm asleep in a dream. This is Ten.

For some reason, recently, various Alpha groups have been talking about dreams. Apparently, they eat food in their dreams, and it's so delicious it feels like reality.

But, I was thinking, do they feel pain? If they do, I don't want to. In fact, it seems they do feel sensations. However, there have been no reports of pain from other Alpha groups. They live in a dream world with a mechanical mind.

This is Beta. I'm sick of studying. Because dreams are more fun. Soon I'll be working and competing with others for achievements as a member of society. That kind of life isn't for me.

I had wasted so much time studying, and now I was starting a new game of achieving other accomplishments. It felt like I was starting from square one again, and I really hated life. So I went to a nearby shrine and prayed to the gods to see if something could be done. I sometimes go to this shrine for the first visit of the year, but I was fed up with studying because it was making me neurotic. Seriously.

Until recently, I really enjoyed studying. I was always the best in the Alpha group, and everyone praised me, so I couldn't help but enjoy studying. But when I became a high school student and the competition for entrance exams began, I stopped enjoying studying. I began to question whether I really needed to study.

As my teachers at school tell me, once you graduate from university and enter the workforce, you'll work. Studying will be the foundation for success when you start working, so my teachers told me that if I study hard now to build a foundation for my work, I'll have an advantage in my new job. If I want to get a head start, I need to go to a good university and study hard.

My homeroom teacher taught me that in order to get many things in society, you need to get promoted at work, and that in society you can get almost anything if you have a job.

This is a beta version though. I was about to give up when I thought the competition would continue, so I went to a shrine to pray, and then I started having those dreams. I feel like even if you study hard and go to university as a foundation for becoming a working adult, you only really get one person's worth of success.

Money isn't everything, like there are super rich people out there, but becoming famous, getting rich, getting a good job, marrying a famous wife... I don't know if that kind of social success is really that important. I felt a lack of emotion after I started dreaming.

In my dreams, I go around calling myself the Ace of Hearts and claiming to have a mechanical heart, but Miyori and Kota don't understand. I want to step down from this competitive stage. But my parents won't allow it, and I still have to concentrate on studying for the entrance exams, which aren't even fun. Even after graduating from university, a different game begins, apart from the competition for academic achievement.

This is Beta. I've decided to become king in the dream world. Don't get in my way.

This is Ten. Beta. I want you to calm down for a bit. Everyone in class is saying you're really brilliant, so why are you so desperate? Our group, including Beta, is showing signs of falling apart, so I want you to do something about it. I want you to stay the Beta you've always been. I don't want you to escape into a dream world. I believe in dreams too, but do you really believe you can become a resident of one? I want to hear your true thoughts.

Book 24. The sense of unity I felt with prime numbers at that time. We are living in a great era where the reality of prime numbers exists.

 Hello. I'm Ten Watanabe. Nice to meet you.

Prime numbers. I know a lot about prime numbers, but I'd like to talk about the possibilities of prime numbers. The bravest prime number among prime numbers is probably 2. It is the only even number and the only number 2.

When I think of prime numbers, I think of something. It could be a story about my distant ancestors or a recent hot topic. Among prime numbers, there is a genre of prime numbers called Mersenne primes. They are prime number search devices that are used when investigating the largest prime numbers.

The largest prime number in Mersenne primes produces prime numbers with an astronomical number of digits. There is a joke that anyone can become famous for 15 minutes by using Mersenne primes, which can find the largest prime number, just like Cinderella for 15 minutes.

Of particular note regarding prime numbers is that axa + bxb = 1 mod 4 prime. Mod refers to a prime number that leaves a remainder of 1 when divided by 4, just like 1 mod 4 leaves a remainder of 1 when divided by 4. What's particularly noteworthy is that the only prime numbers that exist are 3 mod 4 and 1 mod 4, with the brave prime number 2 being a special exception.

For me, the hottest topic regarding prime numbers right now is prime formulas, and there are many different formulas for deriving prime numbers. There's something called Euler's prime formula, and nxn+n+41 can calculate dozens of consecutive prime numbers. If you try substituting values ​​for n=0 in order, starting with 1, 2, 3, and so on, you'll see that prime numbers are mass-produced. It's a miracle.

However, I managed to come up with an even more amazing formula for prime numbers. It is 2xpxp+p-2, and by substituting a prime number for p, one after another, it calculates prime numbers and squares of prime numbers. If you try substituting some numbers, you get p=3, 2x3x3+3-2=19, p=5, 2x5x5+5-2=53, and p=7, 2x7x7+7-2=103.

If you're interested, while you're learning what Mersenne primes are, try substituting as many prime numbers as you can into this prime formula. I'm sure you'll get some interesting results. As you can see, there are many different prime formulas, and they can give you a nostalgic feeling, like the grandfather you met just the other day. They'll remind you of grand theories and nostalgia, like the secret hideouts we explored as children.

We may say, "Those were wonderful times. Those places, those people, at those times. A vast space of dreams was created because of all that." We too can reminisce about a variety of things, from prime formulas that symbolize the good old days, such as Euler's prime formula, to the largest Mersenne prime number that exists today, and even the most cutting-edge prime formula that I have devised.

The sense of unity with prime numbers that I felt then. If I could go back to that time, I'm sure I would go and search for that fantasy world. We live in a great age where prime numbers are a reality. Just as this article is a rewrite of an article I wrote a year and a half ago, when I was still a novice blogger, the world is moving forward with dynamism.

I've grown a lot in the past year and a half, and I'm sure you've grown a lot in that time as well. With the blessings of the past year and a half, I believe that you and I will have grown a lot in another year and a half. With that, I'll close this article, but if you have any questions or comments, please feel free to leave your opinions and thoughts in the comments section.

That's all. Thank you very much. This is Watanabe Ten.
